Search for High Energy GRB Neutrino Emission with ANTARES [PDF]
arXiv, 2013 ANTARES is the largest high-energy neutrino telescope in the Northern Hemisphere. A search for neutrinos in coincidence with gamma-ray bursts using ANTARES data from late 2007 to 2011 is presented here. An extended maximum likelihood ratio search was employed to optimise the discovery potential for a neutrino signal as predicted by the numerical ...

On a dislocation density based two-phase plasticity model: refinement and extension to non-proportional loading [PDF]
arXiv, 2013 The two-phase composite approach of Estrin et al. (1998) describes an evolving dislocation cell structure. Mckenzie et al. (2007) enhanced the model to capture the effects of hydrostatic pressure and temperature during severe plastic deformation.

Microstructure and strength of metals processed by severe plastic deformation [PDF]
, 2006 The microstructure of f.c.c. metals (Al, Cu, Ni) and alloys (Al-Mg) processed by severe plastic deformation (SPD) methods is studied by X-ray diffraction line profile analysis.

Luminosity dependent accretion state change in GRO J1008–57
EPJ Web of Conferences, 2014 In a former publication, we have analyzed the transient neutron star X-ray binary GRO J1008–57 using all available RXTE-, Swift-, and Suzaku-data. As we have found, the source’s spectral components, i.e., a power-law with high exponential cutoff and a ...

Crystals, 2019 A fine-grained Mg-2Y-0.6Nd-0.6Zr alloy was processed by bar-rolling and equal-channel angular pressing (ECAP). The effect of ECAP on the microstructure and mechanical properties of rolled Mg-2Y-0.6Nd-0.6Zr alloy was investigated by optical microscopy ...

A multi-model approach to X-ray pulsars
EPJ Web of Conferences, 2014 The emission characteristics of X-ray pulsars are governed by magnetospheric accretion within the Alfvén radius, leading to a direct coupling of accretion column properties and interactions at the magnetosphere.

The Physics of Accretion Onto Highly Magnetized Neutron Stars [PDF]
arXiv, 2019 Studying the physical processes occurring in the region just above the magnetic poles of strongly magnetized, accreting binary neutron stars is essential to our understanding of stellar and binary system evolution. Perhaps more importantly, it provides us with a natural laboratory for studying the physics of high temperature and high density plasmas ...

High-resolution studies of the twin jet in NGC 1052 [PDF]
arXiv, 2008 The radio loud galaxy NGC 1052 is being studied in an intensive multi-band campaign including X-ray brigthness monitoring and spectroscopic observations, single-dish radio brightness monitoring at centimetre wavelengths, and a high-frequency very-long-baseline interferometry monitoring program. Here we present a progress report on our studies from this

Spontaneous Interlayer Charge Transfer near the Magnetic Quantum Limit
, 1997 Experiments reveal that a confined electron system with two equally-populated layers at zero magnetic field can spontaneously break this symmetry through an interlayer charge transfer near the magnetic quantum limit. New fractional quantum Hall states at
